MACHINE FOR HANDLING MTERIALS.

Application filed Gctober 19, 1923.

This invention relates to loading machines, such as may be used for gathering loose materials and loading the same on conveyances for removal, and to machines oi' similar character.

@ne et the objects of this invention is to provide a powei` operated machine by which a load of material, such as earth, gravel and the like, may be gathered and elevated for transportation or for depositing in al conveyance for transportation. Y

Another object of this invention is to provide a machine by means of which suoli a load may be elevated to a suiiicient height to be deposited in a conveyance having an elevated body.

Another object ot this invention is to provide suoli a device by which the loan mayV be not only lifted, but swung to either side Jr'or depositing in a conveyance.

Another object ot this invention is o provide a machine by which these various operations maybe carried out and which may be driven and operated by a single operator.

Another object of this invention is to provide such a device which may be applied to a power vehicle of standard construction.

Further objects will appear from the detail description taken in connection with the accompanying drawings, in which:

Figure 1 is a side elevation, partly in section, ot' a machine embodying this invention; Y Figure 2 is a plan view of the same; and

Figure 3 is a detail sectional view of the arrangements t'or swinging the load.

Referring to the accompanying drawing, l designates a. power propelled frame provided 'with traction wheels 2 and steering wheels 3. This may take the form of an ordinary tractor ot' any suitable design. The embodiment illustrated in the drawings is shown as applied to a. tractor of what is known as the Fordson type.

Mounted on the front of the trame 1 is a suit-able bracket 4 upon which is mounted an upright column 5 suitably braced lby means of braces 6 so as to maintain the same in upright position. The column 5 has an internal section 7 mounted for rotary and vertical sliding movement in the section 5 and forming therewith a telescoping column adapted to be extended upwardly so as 'te increase the normal height of llitt The Serial No. 669,541.

section 7 is pro I*ided at its upper end with a horizontally extending boom 8 which may be elevated by elevating the section 7 and which may be swung laterally by rotating the section 7. The column 5 7 as well as the boom 8 may be formed of hollow pipe and the boom has suspended therefrom by means of cables 9 and 10, a bucket or shovel 11.

Mounted on a bracket 12 fixed within the -lower end ot' the section 5 is an upright hollow column or post 13 carrying at its top a flange 14 fitting within the section 7 and adapted to act as a guide therefor. The cables 9 and 10 each have one end anchored to the boom 8 and pass downwardly over a pair of sheaves 15 on the shovel 11, then upwardly to the boom 8 passing through openings in the pipe to the interior thereof, then over a pair of sheaves 16 mounted in the boom 8 to a pair of sheaves 17, only one ot which is shown, to the interior of the column 5 7. lithin the columns the cables pass downwardly around a pair of sheaves 18 fixed within the'lower end of the section 7, thence upwardly and around a pair of sheaves 19 mounted on the flange 14, thence downwardly through the interior of the post 18 and around a pair of sheaves 20 to the outside ot the column 5. @nly one of each of the sheaves 18, 19 and 2() is shown in the drawings so as to avoid confusion. After passing f f out of the column 5, the cables pass upwardly between said column and the front ot' the tractor frame to a pair ot sheaves 21, each mounted on the end oit one of a pair ot' levers 22 and thence over a pair of sheaves 23 mounted on the opposite ends of said levers. litter passing over the sheaves 23, the cables pass downwardly to a winding drum 24 mounted on the side of the trame 1. The ends of both cables are ixed to the drum 24; andthe cables are wound thereon simultaneously so that, considering for t-he moment that all the sheaves over which the cables pass are stationary, the shovel 11 will be lift ed by both cables alike as they are wound up by the drum 24.

The drum 24 is connected by means ot a suitable clutch and brake device 25 o t' any well known construction to a worm gear driven by a. shaft 27 operated by the power plant of thev'ehicle in any well known` inanner. The 'clutch and brake device 25 may las epratd by means of a suitable central 'of the cables acting through the sheaves lever so that as soon a.; the clutch connvcts the drum tor driving engagement, the brake is released and vice versa.

lilounted on the boom 8 and below the yame a bracket 29 carrying a halt round har extending crosswise ot the boom. The shovel ll is provided with a pair o't channels 3l extendingt'roin front to rear thereot and adapted to engage the cross-bar llt) when the shovel has been `elevated to a snll'icient height.

The section 7 is tree to move vertically within the section 5, while the post l3 stat'onary. lt will be clear, therefore, that when the shovel ll has been elevated until the abutments engage the cross-bar 30, it' the drum Zit continues winding, the tension lt; vand 19 will cause the section T to be l ted vertically in the section 5'. This vertical movement may continue until arre ted by a suitable stop as will be heren l icribed.

ln order to provide Vfor rotating the section T- a collar 32 is secured by `means ot m to the upper end ot the .folunin 5.

screws o@ rllhe collar 92 is provided with an overturned edge 3ltaking over a ring 35 mounted loosely on the upper end ot the column 5 and -havaig secured thereto a bevel gear 3G. rlhe ring 35 is loosely conned between the upper edge ot the Column 5 and 'the over-turned edge of the collar so to be rotatable on .the upper end of `the column. The r 35 is provided with inwardly extending id diznnetrically opposite lugs 3T, each adapted to work in a slot 38 in the section T. i

bevel gear 39 adapted to mesh with the gear" 3G is journalled in a bracket d() mounted on the bracing G and connected by means o t a universal joint LIrl with a control rod provided with an operatingy hand wheel 4l?) tor manipulation by the driver. iihen the section 7 is lifted vertically bythe operation ot' the cables, the lugs 37 rde in the slots but when the gear 39 is operated, the ring 35 will be rotated and by engagement et the lug-,rs 3T will rotate the section 'T so as to swing the boom til to one eide or the otl er. The operator is thus able to lift the lead to any cesired height and then svv the shovel laterally so as toiduinp the load into a high bodied conveyance standlng alongside of the machine. The ends et the slots 3S, acting Yiinst the-lugs 3T, lno'vide to limit the l. t of the section 7.

The levers 22 are pivoted at the common axle ot the two sheaves 23 on a bracket 4l mounted on the bracing 6. vThe' other endsot' these levers are hung each on one end oit' a cable which passes from the end of one lever .22 up over one oit a pairot sheaves (3,

then downwardly to a drum et? mounted on a. bracketl on the bracing 6 and to which the middle ot the cable is tastened7 thence back over the other sl'ieave 46 and to the other 'tiorn the load `in ythe drum 1li' to tiil @he on the otherhand themachine is b lever 22. Thus the cable has its nrddlc point lixed to the drum L7 and its two ends supporting the two levers 22.

It will be clear that by rotating the drum 1li' by means of a manipulative hand wheel 118, one ofthe levers 22 will be elevated and the other lowered an equal amount. This will have the eti'ect ot' correspondingly taking up one and slacking ott the other ot the Vcables 9 and l0. lt w ll also be clear that since both levers Q9 are pivoted on a commen pivot and are moved equally `by the operation et the d ruin l?, the ell'ectivc lengthening of one of the cables t) and l() will be equal to the corresponding shortening oit the that the same may ether be tipped b::;ci; so as'to carry the load withoutspilling, or 'tipped forwardly so as to dump the load. Furthermore since the cross-bar il() roi on the bottom, the 'channels 3l when in r tact therewith may rock about said cross-bar as the cables 9 and ltlare lengtl'iened or shortened so that the shovel ll may be adjusted or tipped either when hanging tree or when in engagement with the abutment 30. rlhe hand-wheel 418 may be equ'pped w th a brake 4S) release-ble by a suitable handle so that when the shovel has .once been adjusted tor posit-ion,y it maybe held in that position.

ln the operation ot this device the operator may `lower the shovel ll to position for gathering up the load and Y ihen drive the tractor t renard so aste shovel up the material. An Vlabutment''l on the bucket is adapted for suitable engagement with the front of the bracket l or other suitable part of the oevice so aste propel the shovel 'for filling the saine. After illing the shovel7 the drum l-T may be operated so as lo tip the trout end iii-pwardly in order to carryr the load withoutl spilling. It now the load is merely to be transported and dumped n another locality7 the shovel may be ele fated to any positiiiin-above the ground and the tractor may 'then be propelled so as to transport theload. 'fitter arriving at its destinaay ybedumped by operating J shovel torwaiidl Afor loading` carts or other coirfeyanees, auch a-cart may be drawn -upnlrnig sde o't the machine. In `this case the shovel may be elevated until thechannels 3l engage the abutment 30 and-then it' necessary the column 5-7 maybe extended vthrough the operation ot the cables 9 and l() by simply continuing to wind `up lon thedrum Q-l. .filhen'the required elevation has been olitained, the hand-wheel l may be operated to rotate the section 7 and swing the boom wlth its load laterally over the conif'eyanee to receive the load. The l'nicket .may then be tipped as above described so as to dump the load into such conveyance. ll it desired to use the machine for excavation, the shovel may be lovvered to the ground vvitl ihe point tipped forwardly, and then propelled forwardly by operating the tractor, 'lhe load may then be elevated and dumped as described above. ln the service suitable bracing as indicatei'l at 52 may be advisable lo transmit the thrust oi the digging operation to the traction Wheels.

lt Will be evident, thereiore, that the device accomplishes its objects. r"he shovel ll may be manipulated for gathering and for elevating the load. Such elevation may be just enough to transport the load to another locality or the shovel may be raised to any desired height by extending the tele,- sl oping column through proper operation of the cables 9 and rl'he position of the shovel may be adjusted as desired either before or during elevation orV When elevated. ritter elevating the column, the load may be swung to either side so that it unnecessary to move the tractor body' in order to adjust the shovel over the conveyance Which is to receive the load. rThe manipulative controls 1re all located Within easy reach of the driver Who is the sole operator o1e the machine.
